# SMTP Error: Data not accepted

 * I am suddenly having an issue where an order has been placed but the emails from
   Woocommerce are not being sent. I am using WP Mail SMTP. The “from” address is
   the one hosted with the site through one.com. The email address these emails 
   should be sending to is a Yahoo one. I have ticked the “force from” box and checked
   the SMTP settings with one.com but the issue persists. Sending a general test
   email works just fun, the error is only for emails triggered in Woocommerce.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fsmtp-error-data-not-accepted-13%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Thank you. I have checked with the hosting provider and all is in order yet the
   issue persists. Emails from Woocommerce send in plain text but not html which
   gives the error. A test email sent from WP Mail Smtp is delivered without issue.

 * Hi [@katewfff](https://wordpress.org/support/users/katewfff/)
 * Since you’re using WP Mail SMTP for sending emails, which re-routes your emails
   through a 3rd party email service provider, if the plugin is not working as expected,
   I would suggest you reach out to the WP Mail SMTP support team directly: [https://wordpress.org/support/plugin/wp-mail-smtp/](https://wordpress.org/support/plugin/wp-mail-smtp/)
 * Thanks.

 * Thanks, I will do so. Although all other emails from the site are working as 
   they should through WP Mail SMTP, just not those triggered by WooCommerce.

 * Hi [@katewfff](https://wordpress.org/support/users/katewfff/)
 * Thanks for letting us know.
 * If the problem remains unresolved even after contacting WP Mail SMTP support,
   then please send over a screenshot of the email settings (WooCommerce > Settings
   > Emails) and we’ll take a look.
 * Cheers
